If I use Find, the document I found the text in leaks, along with a few chrome documents, such as chrome://global/content/platformHTMLBindings.xml. Details that might or might not matter: * I start Find with Cmd+F, type some text that exists in the page, press Esc, and then quit the browser immediately. * If I select text by dragging instead of using Find, nothing leaks. * The patch on bug 315708 doesn't seem to help. * I tested on http://www.squarefree.com/start/ and http://en.wikipedia.org/wiki/1 through 5. Setup: * This is with a trunk debug build on Mac with dbaron's leak-detecting stuff. * I disabled all of my extensions before testing.

This fixes at least the main leak, which was two leaked references to a pres context for each call into this code.

I tried the patch. The leaks of chrome:// documents are gone. Now I just see a DOMWindow leak: Leaked outer window 20af33e0 at address 20af33e0. Leaked inner window 226802d0 (outer 20af33e0) at address 226802d0. ... with URI "http://www.squarefree.com/start/"".

That last leak may well be fixed by bug 315708, and in any case I think I've tested that it's just a single object held longer than it should be (and if you repeat the action, another one replaces it).

Fix checked in to trunk.

Is this bug really specific to Mac OS X?

No.
